N. Mex., by Elisama Embry, administratrix, 1821 Truman NE., Albuquerque, N. Mex. 87110 Fiied Sept. 28, 1967, Ser. No. 671,927 Int. Cl. A44b N34 US. Cl. 24-107 Claims ABSTRACT OF THE DISCLOSURE A two-part snap-on button is disclosed for either factory application to a garment or for replacement of a conventional button on a garment when it has become separated therefrom. The fabric of an underlying layer of a garment, as that of a shirt is interposed, in a recess of the head of the button between the head of the button and a head on the stud part of the button, with the fabric clamped between the head of the button and the stud. The dimensions of parts is such as to provide a clearance between the underlying layer and the underface of the button head to enable an upper layer of the garment to be buttoned over the head in conventional fashion.

The invention relates to a button which may be snapped onto the layer of a garment so that another button holed layer of the garment may be buttoned thereover.

An object of the invention is to provide a means whereby a button may be applied to an unperforated portion of a garment by simplypressing two parts of the button together and yet provide a space between the two parts so that a second layer of the material may be buttoned over the head of the button.

Other objects will become apparent after a consideration of the following specification when taken in conjunction with the accompanying drawing in which FIG. 1 is a cross sectional view of a two-part button snapped together with an imperforate layer of cloth between the two parts and a perforate layer buttoned over the head of the button.

FIG. 2 is a top plan view of the head of the button,

FIG. 3 is a top plan view of a stud portion of the button, and

FIG. 4 is a side elevation of the stud portion of the button.

Now referring to the drawings in greater detail, the snap-on button is comprised of the cylindrical head and the stud 12. The top surface of the head may be configurated as desired. As here shown the top surface is recessed as indicated at 1-4, the bottom of the recess being configurated to simulate button holes 16 and threads 18. The bottom surface 20 of the head is substantially planar except for a projection 22 in the form of a truncated cone extending downwardly of the button. Centrally located in the projection is a recess 24 which may extend upwardly into the head beyond the level of the bottom planar surface. The recess is surrounded at the bottom of the cone by a restricted mouth or turned in flange portion 26.

The stud portion of the button comprises a cylindrical base 28, a concaved shank and an enlargement 32. The base preferably is of a diameter less than the diameter of the head of the button and the shank and enlargement thereon are of a height slightly greater than the depth of the recess in the projection and head to allow for the thickness of a fabric clamped in the recess of the head spacing the stud base away from the under planar surface 20 of the head. Likewise, the maximum diameter of the enlargement is slightly less than ice the diameter at the mouth of the recess to allow for thickness of fabric, but yet close enough in dimension to cause some springiness of the mouth of the recess to take place when the stud and head of the button are assembled with the fabric therebetween. As illustrations only of the size of parts and not intended as limitative factors, the shank and enlargement may be .090" in height while the depth of the recess in the head is .070". Again, as illustrative only, the maximum diameter of the enlargement may be .124" while the diameter at the month of the recess is .134". The thickness of the base of the stud is of the order of .080". It will be noted that the mouth to the recess in the head has rounded lips and the shank and enlargement have rounded configurations to avoid cutting of the fabric when the button is being assembled and while it is in use.

While in a preferred form the head of the button is made of resilient plastic material, the resiliency may be obtained by making the shank and enlargement of spring material as a plastic material or of springy metal by vertically slitting the enlargement.

The snap-on button may be applied to a garment in a factory or elsewhere as an original part of the garment or may be applied thereto subsequently, as to replace a button which had originally been sewed on the garment and had become detached.

To apply the snap-on button to a garment one merely applies the head of the button to the upper face of an underlying layer of a garment and applies the stud to the lower face of the same layer. When the two parts of the button are pressed together they will snap into position with the layer of material gripped between the two parts of the button. Because of the projection on the underside of the head of the button and the formation of the shank and enlargement, a considerable clearance will exist between the under planar face of the head of the button and the upper face of the layer of fabric to enable buttoning a second layer of material over the head of the button and positioning of the fabric in that clearance.

What is claimed is:

1. A two-part button including a head and a stud,

said head having an upper and lower surface,

the lower surface being substantially planar except for a projection extending from said lower surface and located so as to provide a flange on said head surrounding said projection,

there being a recess with restricted mouth facing downwardly in said projection,

said stud comprising a base member larger in diameter than the recess and an upstanding shank with an enlargement thereon of a size slightly smaller in diameter and greater in height than the largest diameter and the depth respectively of the recess, at least one of the head and stud being of resilient material whereby a fabric may be clamped between the head and stud when the fabric is fitted over the upstanding shank on the stud which shank is forced into the projection recess of the head to provide a two-part button wherein the head and stud are spaced from each other while clamping the fabric therebetween.

2. A button as set forth in claim 1 in which the head is made of resilient material.

3. A button as set forth in claim 2 in which the head material is a plastic.

4. A button as set forth in claim 1 in which the head is circular in plan and the shank is a projection centrally of the base member.

5. A button as set forth in claim 1 in which the mouth of the recess, and the enlargement have rounded surfaces.
